PhD title: Processes affecting gas transfer velocity along latitudinal gradients and the impact on global CO2 air-sea flux estimates
The global ocean is a major sink for anthropogenic CO2. This uptake slows down the rate of climate change, notably global warming. However, uncertainty in the gas transfer velocity contributes about 20% uncertainty to estimates of the global net ocean CO2 uptake. Consequently, a key point in estimates of ocean carbon uptake is to develop an accurate gas exchange model and to reduce the uncertainty in the gas transfer velocity.
1. Process the ship-based CO2 flux data, calculate the gas transfer velocity.
2. Investigate how different processes affect the gas transfer velocity along latitudinal gradients.
3. Explore the influence of spatial variation in the gas transfer velocity on global CO2 air-sea flux estimates.
